Dynamics of long-distance signaling via plant vascular tissues. Environmental stress conditions change either rapidly or incrementally. 9 (8), e29518. Because proline biosynthesis and degradation occur in mitochondria, the accumulation of toxic compounds such as P5C may cause damage to plant cells under severe abiotic stress (Rizhsky et al., 2002; Rizhsky et al., 2004). Some plants are naturally adapted to dry conditions, surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. doi: 10.1042/BJ20071115, Taji, T., Ohsumi, C., Iuchi, S., Seki, M., Kasuga, M., Kobayashi, M., et al. Proc. Overall, transport assays in insect cells expressing NPF4.6 demonstrated that this transporter mediated cellular ABA uptake into cultured cells (Kanno et al., 2012). Plant Cell 31 (1), 84–105. Therefore, the CLE25–BAM1 and BAM3 systems control ABA accumulation and responses, including stomatal closure and stress-inducible gene expression.

These results indicate that the increased tolerance to freezing stress in transgenic plants overexpressing AtDREB1A may depend on the accumulation of low-temperature regulated metabolites, especially sucrose, raffinose, galactinol, and myo-inositol. Together, these data indicate that MtABCG20 is an ABA transporter that influences root morphology and nodulation in Medicago truncatula (Ding et al., 2008). Natl. Plant Signaling Behav.

In particular, the dehydration-inducible accumulation of branched-chain amino acids (BCAAs), saccharopine, proline, and agmatine is correlated with the dehydration-inducible expression of their key biosynthetic genes (branch-chain aminotransferase 2; AtBCAT2, lysine ketoglutarate reductase/saccharopine dehydrogenase; AtLKR/SDH, delta 1-pyrroline-5-carboxylase 1; AtP5CS1, and arginine decarboxylase 2; and AtADC2, respectively), which are regulated by endogenous ABA (Urano et al., 2009). doi: 10.1074/jbc.M109.096644, Jones, A. M., Danielson, J. Additionally, MtABCG20 showed subcellular localization at the plasma membrane via homodimer formation in Arabidopsis mesophyll protoplasts. (2013). 161 (2), 942–953. Nodulation is a unique process in legumes, and ABA acts as a negative regulator of nodule primordium formation in the root cortex tissue (Ding et al., 2008). Plant J. States America 97 (9), 4967–4972. These results indicate that plants regulate stomatal aperture via various signals that are generated at different times during prolonged dehydration stress conditions (Figure 1). BMC Plant Biol.

AtABCG31 and AtABCG30, as well as AtABCG25 and AtABCG40 described above, were shown to serve as ABA exporters and importers, respectively, in Arabidopsis seeds (Kang et al., 2015). doi: 10.1105/tpc.105.035881, Sato, H., Takasaki, H., Takahashi, F., Suzuki, T., Iuchi, S., Mitsuda, N., et al. Many genes have been tested in greenhouses, but few of them have proven to be useful in the field. On the other hand, other T-DNA mutant lines of athk1 did not show a significant difference in ABA accumulation compared to that of control plants under low water potential and instead displayed an increased density of stomata (Kumar et al., 2013). HPCA1 belongs to subclass VIII-1 of Leucine-Rich-Repeat Receptor-Like Kinase (LRR-RLK), which is localized to the plasma membrane. On the other hand, the receptors that bind with peptides are expressed specifically in each tissue. Genes involved in metabolite synthesis in diverse abiotic stress responses are useful for application in the metabolic engineering of stress resistance in dry field conditions. Maruyama et al. Plant Physiol. Annu. In addition, abscisic acid (ABA), a plant stress hormone, induces the closure of leaf stomata, thereby reducing water loss through transpiration, and decreasing the rate of photosynthesis. As for one example, the decreasing water potential status is an initial step that plants recognize dehydration stress conditions (Christmann et al., 2013). 61, 651–679. Biochem. 50 (6), 967–981. 164 (4), 1587–1592. These novel findings suggest that peptides function as mobile molecules in the plant vasculature for the integration of water deficit stress signals in long-distance organ-to-organ communication. It is therefore essential to breed water-saving and … J. Exp. Proc. Soni, P., Nutan, K. K., Soda, N., Nongpiur, R. C., Roy, S., Singla-Pareek, S. L., et al. Root-associated microbes can improve plant growth, and they offer the potential to increase crop resilience to future drought. These genes are the “building blocks” that Dr Yang referred to, which had evolved independently in a process known as “convergent evolution” to produce the same mechanism in all three species. Drought-induced loss in crop yield probably exceeds losses from all other causes, since both the severity and duration of the stress are critical. 24 (1), 25–37. (2015). This could allow crops to be grown in previously impossible environments, or provide them with greater resilience when faced with unfavourable climates. Transcript and metabolite profiling during cold acclimation of Arabidopsis reveals an intricate relationship of cold-regulated gene expression with modifications in metabolite content. Nat. Science 313 (5788), 842–845.

The CLE9-induced stomatal closure is not inhibited in the bam1 and bam3 mutants, indicating that some other RLKs mediate the CLE9 signaling in guard cells. Further analyses including the isolation of molecules directly downstream of ATHK/AHKs will help us understand ATHK/AHK signaling in plants. Science 331 (6017), 582–585. The ROS/Ca2+ wave that is generated by light stress propagates rapidly from local leaves to systemic leaves at a speed of 100 μm/s and, in turn, mediates the initiation of ABA and jasmonic acid (JA) biosynthesis.

In another transporter family, Arabidopsis thaliana DETOXIFICATION EFFLUX CARRIER 50 (AtDTX50), which belongs to the multidrug and toxin efflux transporter (MATE) family, has also been identified as an ABA transporter in Arabidopsis (Zhang et al., 2014). Abscisic acid dynamics in roots detected with genetically encoded FRET sensors. In vitro yeast accumulation assays demonstrated that the Lr34res protein resulted in increased ABA uptake in yeast cells, suggesting that LR34res might act as an ABA importer. In this review, we summarize recent knowledge of how long-distance signaling, ABA transport and metabolic regulation mediate drought stress responses and resistance in Arabidopsis and crops. Various membrane proteins function in ABA transport in different tissues, which indicates that complex systems are involved in ABA transport in plant physiology.

There are ABA receptors in almost cells. The blue line indicates the local signals of ROS/Ca2+ waves, peptide, or ABA signals that mediate stomatal control under stress conditions. These data indicate that AtDTX50 might modify ABA transport in both vascular cells and guard cells (Zhang et al., 2014). (2011).
